SPECIFICATION forming part of Letters Patent No. 341,695. dated May 11, 1886,

Application llled January 18, 1886. Serial No. 68,990. No model.)

To all whom it may concern:

Be it known that I, SAMUEL J. SHAW, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvementin Ventilating \Veather-Protectors for \Vindows of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The object of my invention is to provide a simple and inexpensive weather protector or shield to be used in connection with open win- (lows for the purpose of keeping out rain, snow, &c., while admitting fresh air to the room.

The invention is embodied in a device cousist-ing of two or more sections arranged to slide telescopically upon one another, to fit windows of different widths, the said pieces consisting of a front portion which, when the device is in position in the window-frame, inclines downward and rearward from a point in front of the lower part of the window-sash to the sill, and end pieces extending to the window -frame and provided with engaging devices forengaging the windowframe in front of the sash, and serving to hold the device in position. The said engaging devices may be provided with a longitudinal groove to receive the screws by which the sash-holding strip is fastened to the window-frame, or the bead sometimes used for holding amosquito-screen.

Figure l is a perspective view of a windowframe provided with a weather-protector e1nbodying this invention; Fig. 2, aplan view of the said weather-protector, and Fig. 3 an end elevation thereof.

The device consists of two or more pieces, which may be made of sheet metal, and each of which consists of a front portion, a a,which, when in position in the window-frame, as shown in Fig. 1, has its upper edge a few inches in front of the lower part of the sash A, and inclines rearwardly and downwardly from said upper edge to the window -sill, as shown. The front portions, a a, of the two pieces are connected to slide telescopically up on one another, each being provided with ears Z) b, which overlap the other. The end sections, a a (see Fig. 2,) are provided with end pieces, a, which extend hack to the jambs of the windowframe, as shown in Fig. 1, and are provided with engaging devices 0, which engage the said jambs, as shown, when theend sections are placed in the window-frame and drawn apart to the full width of the said frame. The parts when thus separated and pressed against the jambs may be fastened by a suitable clamp; or, if desired, a spring may be arranged to push the parts outward, and the engaging devices 0 may be strips of rubber, which, by their adhesion, will afford a firm hold on the woodwork without injuring the surface thereof, the protector being held fast in the window-frame by longitudinal or end pressure against said frame. The shield or weather-protector being thus securely held in the window-frame at the front ofthe sash, the latter may be raised or lowered as much as desired, in order to admit more or less air, and the shield will serve to prevent rain or snow from coming into the room, and will at the same time deflect the fresh air upward, as is desirable for the proper diffusion of the air. The space at the back of the inclined shield and between the end pieces is wholly unoccupied, thus permitting the front pieces to overlap one another for their entire length,when necessary; and the sash may, if desired, be wholly shut and locked without removing the protector from the window-frame.

\Vhen desired to accommodate a greater difference in the width of windows than can be accomplished by two sliding pieces, the apparatus may be made in three parts, as shown in Fig. 2, the ears I) I) of the adjacent parts a a being at the edges of said parts, and the ears b of the part a engaging long grooves or slits b in the portion a, while the ears of the portion a engage similar slits, b", in the portion o the said ears being struck out from the metal, and the openings 1) made by striking up the ears from the piece a, only showing in Fig. 2, as the said ears themselves are at the other side of the piece a The engaging devices 0 are preferably provided with a longitudinal groove, 0", to receive the heads of the screws by which the sashholding strip B (see Fig. 1) is attached to the windowframe, as shown in Fig. 1, or to receive the projection or bead that is sometimes fastened to the said strip B, for the purpose of holding screens.

I am aware that a ventilator has been made composed of two parts which have a limited telescopic movement with relation to one another, and have end pieces which enter the sash-groove below the sash, which rests upon the ventilator and holds it in position in the window-frame; but such a device does not permit the sash to he raised or lowered to regulate the amount of air admitted, nor to be wholly closed while the ventilator remains in position.

I claim- 1. In a ventilator of the character described, the deflector composed of longitudinally-adjustable sections provided with triangular pieces at their outer ends,which have cleats on their outer faces to engage the plain surface of the window-frame, in combination with the SAMUEL J. SHAW.
